The dock “thinks” for itself 23.05.2019
Decentralised Control in Bulk Material Handling

The world of bulk material handling seems easy at first glance: moving, filling, delivering. The art of dealing with a variety of different materials, however, lies in the details, such as the docking and undocking of containers at weighing stations. In the process, crosscontaminations

and the release of dusts can occur. AZO CleanDock prevents this

problem. Its latest generation can do even more: it “thinks” for itself. Directly attached to the dock, the integrated controller CEC of the modular electrical terminal CPX from Festo ensures additional process security and shortened commissioning times.
